Embodiment Construction

[0037]The present invention will be explained in detail below in conjunction with the cruise flight example.

[0038] After the cruising mission starts, the UAV performs cruising flight in a fixed cruising route. During the flight, the ground video is obtained through the UAV pan-tilt module and sent to the video processing module. The video processing module performs relevant preprocessing on the image, and through the accelerated robust feature detection and matching of each frame of image, the relative ground motion of the camera and the UAV is obtained. The motion information obtained by this module is used to match and cut the video, and the local area image set is obtained, which is input into the exception processing module. The abnormal event detection module automatically extracts the trajectory information of the moving object, and judges the abnormal event according to the trajectory information of the moving object through an unsupervised abnormal detection algorit...

Abstract

The invention discloses an abnormality and violence detection system and method based on unmanned aerial vehicle movement monitoring. The invention includes a drone platform module, a cruise flight control module, a video processing module, an abnormal event detection module, a violent behavior detection module and an alarm module. The video processing module is used to receive the data of the UAV pan / tilt module and the cruise flight control module, and preprocess it; the abnormal event detection module is used to analyze the video data processed by the video processing module, and analyze the abnormal event video data in it. Perform detection; the violent behavior detection module receives data from the abnormal event detection module, and is used to analyze whether there is violence in the video after the abnormal event detection module detects the abnormality. The present invention realizes a system for abnormal event detection and violent behavior detection on a drone in a cruising state, and can perform detection at a near real-time detection speed during the flight of the drone, and can provide real-time feedback.

Description

technical field [0001] The present invention relates to the field of unmanned aerial vehicle technology and the field of computer vision technology, in particular to a technology for abnormal event detection and violent behavior detection based on an unmanned aerial vehicle platform. Background technique [0002] The monitoring system is the most important part of the security system. More and more companies and individuals have increased their safety awareness, which has prompted the popularization of monitoring probes. With the substantial increase in camera coverage, the development of various intelligent surveillance algorithms based on fixed surveillance cameras is also very rapid. Thanks to the advantages of automatic operation of algorithms, these surveillance systems are protecting the safety of people's lives and property around the clock. Cameras in various key locations can effectively capture unsafe factors in life. When the fixed video surveillance system is equ...
